There are currently several people and nurseries selling Jerusalem artichoke tubers on EBay Australia. I've just bought the cheapest lot from Sydney NSW.

I could send you some - but pretty sure that’s not possible / legal from Victoria into QLD?

Look up internet seed selling websites. Google - where to buy J A's.

Can I grow sunchokes in containers ? If so does it require anything special and when is the best time to plant?

I have the same question. Hoping someone responds...

Hello I've just been given a huge bag of Jerusalem artichokes. No problems in using them but I want to keep some tubers to plant out at then of winter /spring. Can anyone tell me how to store them until then.

Plant a few them out now. As sunflowers, they are prettier in a north facing spot. They'll be fine as long as they get a bit of water. Be warned they can be quite invasive over a couple of year period if you're not careful.

Do you think I could grow these in the Wairarapa? We have frosts to about -5 in winter.

I’ve seen them growing in a few Wairarapa gardens - not sure if people water them but I’ve also seen them growing along side the Ruamahanga under one of the bridges so I guess it should be fine!

Mike, you can leave the tubers in the ground in warmer areas of NZ, we have done that in Northland. In fact it is difficult to find all the tubers, so they will probably shoot up in the Spring even if you have light frosts.
